1, isiqabu soxinzelelo phambi kokutyabeka apho amandla okuqina aphezulu makhulu kune-1034Mpa isitshixo kunye neendawo ezibalulekileyo phambi kokucwenga kufuneka zibe kwi-200 ± 10 ℃ isiqabu soxinzelelo ngaphezulu kweyure enye, i-carburizing okanye indawo yokucima umphezulu kufuneka ibe kwi-140 ± 10 ℃ isiqabu soxinzelelo. ngaphezu kweeyure ezi-5.
2. I-ejenti yokucoca esetyenziselwa ukucoca kufuneka ingabi nampembelelo kumandla okubopha i-coating kwaye kungabikho ukubola kwi-matrix.
3. I-Acid activation ye-asidi isisombululo kufuneka ikwazi ukususa iimveliso ze-corrosion kunye nefilimu ye-oxide (isikhumba) phezu kwendawo, ngaphandle kokugqwesa okugqithisileyo kwi-matrix.
I-4, i-galvanized ingasetyenziswa zincateyenziwe igalatiokanye inkqubo yekloridi yagalvanized, kufuneka isebenzise izongezo ezifanelekileyo ukuhlangabezana neemfuno zalo mgangatho wokwaleka.
I-5, emva kokukhanya okukhanyayo kufuneka kuqhutywe unyango olulula.
I-6, i-passivation yokususa iinxalenye ze-hydrogen kufuneka ibe yi-passivation emva kokususwa kwe-hydrogen, i-passivation ngaphambi kokusetyenziswa kwe-1% H2SO4 okanye i-1% ye-hydrochloric acid activation 5 ~ 15s.I-passivation iya kunyangwa ngechromate enemibala ngaphandle kokuba kuchazwe ngenye indlela kwimizobo yoyilo.
